Carole has $53.95 and washes cars for $8 each. Carole wants to attend a musical that costs $145.75.

a. Write and solve an inequality to determine the minimum number of cars Carole must wash to be able to buy the ticket to the musical.​

they both would have 24

they both would have 2 successful shots. they would mean that the older brother added 4 point to his score and the younger brother would have added 6 to his score

Answer:

The numbers 3 and 8 and be multiply and get 24. They can also be added to get 11.

Answer:

[tex]\sin 105^{\circ} = \frac{\sqrt{6}+\sqrt {2}}{4}[/tex]

Step-by-step explanation:

We can use the following trigonometrical identity:

[tex]\sin (\alpha - \beta) = \sin \alpha \cdot \cos \beta - \cos \alpha \cdot \sin \beta[/tex] (1)

Where [tex]\alpha[/tex], [tex]\beta[/tex] are angles, measured in sexagesimal degrees.

If we know that [tex]\alpha = 135^{\circ}[/tex] and [tex]\beta = 30^{\circ}[/tex], then the value of the given function is:

[tex]\sin 105^{\circ} = \sin 135^{\circ}\cdot \cos 30^{\circ} - \cos 135^{\circ}\cdot \sin 30^{\circ}[/tex]

[tex]\sin 105^{\circ} = \left(\frac{\sqrt{2}}{2} \right)\cdot \left(\frac{\sqrt{3}}{2}\right)-\left(-\frac{\sqrt{2}}{2} \right)\cdot \left(\frac{1}{2}\right)[/tex]

[tex]\sin 105^{\circ} = \frac{\sqrt{6}}{4}+\frac{\sqrt{2}}{4}[/tex]

[tex]\sin 105^{\circ} = \sqrt{\frac{6}{16} }+\sqrt{\frac{2}{16} }[/tex]

[tex]\sin 105^{\circ} = \sqrt{\frac{3}{8} }+\sqrt{\frac{1}{8} }[/tex]

[tex]\sin 105^{\circ} = \frac{\sqrt{3}+1}{2\cdot \sqrt{2}}[/tex]

[tex]\sin 105^{\circ} = \frac{\sqrt{6}+\sqrt {2}}{4}[/tex]

Answer:

The perimeter of a rectangle is: P = 2x+16

The area of a rectangle is: A = 6x+12.

Step-by-step explanation:

Given

The length of a rectangle = l = 6

The width of a rectangle = w = (x+2)

To determine

The perimeter of a rectangle = P

The area of a rectangle = A

Determining the Perimeter of a rectangle

The perimeter of a rectangle can be determined using the formula

P = 2(l+w)

substitute l = 6 and w = (x+2)

P = 2(6+x+2)

P = 2(8+x)

P = 2x+16

Therefore, the perimeter of a rectangle is: P = 2x+16

Determining the Area of a rectangle

The Area of a rectangle can be determined using the formula

A = lw

substitute l = 6 and w = (x+2)

A = (6)(x+2)

A = 6x+12

Therefore, the area of a rectangle is: A = 6x+12.

Answer:

Step-by-step explanation:

First, consider expressions that include one or more of the arithmetic operations: addition, subtraction, multiplication, and division. The order of operations requires that all multiplication and division be performed first, going from left to right in the expression.

Answer:

x = 4.5

Step-by-step explanation:

First, we can subtract 2 from 20 (20 - 2) to get 18.

Now we know that x has to be multiplied by 4 and have a product of 18.

We can divide 18 by 4 to figure out what x is.

18 ÷ 4 = 4.5

We can check our answer by solving the equation:

4(4.5) + 2 = 20

18 + 2 = 20

20 = 20

Answer:

ײ+x(x+1)(x+2)+(1+x)​ = x²+(x+1)³

Step-by-step explanation:

ײ+x(x+1)(x+2)+(1+x)​   ...look that: 1+x=(x+1)

=x²+x(x+1)(x+2)+(x+1)

=x²+(x+1)(x²+2x+1)

=x²+(x+1)³

Note that:

x²+2x+1=(x+1)*(x+1)​

Addition, 83.6

Step-by-step explanation:

x - 72.6 = 11, x = 83.6

The grandson must add 72.6 to both sides to solve for x.

Given:

A line passes through the two points (3,5) and (-1,1).

To find:

The equation of the line in fully reduced point-slope form.

Solution:

If a line passes through two points, then the point slope form of the line is

[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

The line passes through the two points (3,5) and (-1,1). So, the point slope form of the line is

[tex]y-5=\dfrac{1-5}{-1-3}(x-3)[/tex]

[tex]y-5=\dfrac{-4}{-4}(x-3)[/tex]

[tex]y-5=1(x-3)[/tex]

Therefore, the  point slope form of the line in fully reduced form is [tex]y-5=1(x-3)[/tex], here 1 is the slope of the line.

Answer:

42.6cm

Step-by-step explanation:

The sum total of all the sides of the shape is the perimeter of the shape. Hence;

Perimeter = x+3 + 4 + x+9 + 2x+5

Perimeter = 4x + 21

Given

Area of the figure = 75cm^2

Area = (x+3)(2x+5) + (2x+1)(6)

75 = 2x²+5x+6x+15+12x+6

75 =  2x²+23x+21

2x²+23x+21-75 = 0

2x²+23x-54 = 0

x = -23±√23²-4(2)(-75)/4

x = -23±√529+600/4

x = -12±√1129/4

x = -12+33.6/4

x = 21.6/4

x = 5.4

Recall that;

Perimeter = 4x+21

Perimeter = 4(5.4) + 21

Perimeter = 21.6+21

Perimeter = 42.6cm

Hence the perimeter is 42.6cm

Answer:

$86.8

Step-by-step explanation:

Step one:

Given data

At dinner, the meal cost $22 and a sales tax of $1.87

let us find what percent $1.87 to the cost of the meal

= 1.87/22*100

=0.085*100

=8.5%

Hence the sale tax is 8.5%

Step two:

if the cost is now $80

the sale tax will cost

=8.5/100*80

=0.085*80

=$6.8

The total will be

=80+6.8

=$86.8

Answer:

x = 4

Step-by-step explanation:

You begin by making what is inside the brackets = 0. In other words you will somehow get 0 * brackets + 3 = 3

x - 4 = 0

x - 4 + 4 = 0 + 4

x = 4. When you make x = 4, the inside of the brackets = 0

1/2 * 0 = 0

So you are left with

3 = 0 + 3

and x has been made = 4

Do what's in the brackets before anything else.
